Application led March 30, 1915. Serial No. 18,163.

T o all whom it may concern:

Be it known that I, ULYssEs GRANT Mc- QUEEN, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements inCasement-Adjusters, of which th following is a specification.

This invention relates to easement adjusters.

The 4adjuster herein referred to is particularly designed for use inconnection with that type of easement which is free for vertical slidingadjustment and also for horizontal swinging movement. It is, therefore,deemed advisable to mention and to properly emphasize that among otherobjects in view, the principal points of advantage in the structure liein its adaptability to easements of the kind mentioned and to alsoinvite attention to such features of the structure which satisfactorilycontribute with one another to minimize friction between the workingparts of the structure at the time of the initial opening of thecasement or the closing thereof; and, further, the provision of meanswhich will properly accommodate the vertical movement of the easementand at the same time hold the easement at any desired point in itshorizontal adjustment. j

Another object of the invention is the provision of a easement adjuster,which, on a predetermined movement of the easement in a, horizontaldirection, the easement may be frictionally held in its adjustedposition, but in such manner that will permit of its further manualadjustment in a horizontal direction without the necessity of manuallyactuating the adjuster itself.

Aside from the eXtreme simplicity and practicability of the structure,it is also desired that notice be given the manner in which the frictionbetween the sliding parts of the adjuster can be regulated to suitordinary wear and tear of the parts and to also prevent the Casementfrom being accidentally moved from its intended point of adjustment.

In the accompanying drawings Figure 'l is an elevation of a windowstructure, showing in dotted lines the position of the adjuster onvertical movement of the casement and the normal position of thecasement adjuster in full lines. Fig. 2 is a vertical section throughthe same, showing the easement in a partly-opened position. Fig.

3 is a perspective view of the adjuster.`

Fig. 4 is a longitudinalV section therethrough. Fig. 5 is a transversesection therethrough. Fig. 6 is a longitudinal section through bothmembers of the adjuster and illustrating the means for limiting thesliding movement in one direction of one of the members within theother. y

rEhe adjuster, as stated, is particularly designed for use in connectionwith easements which are free to slide vertically and to also swinghorizontally. The easement shown in the accompanying drawings andillustra-ted at C is of the inwardly opening type. However, it isunderstood that it may be just as effectually used in connection with aeasement which is to swing in an outward horizontal direction if such beadvisable.

The adjuster consists of two mating members 1 and 2, the former being inthe nature of a tube and the latter in the form of a rod, which is freeto slide in a longitudinal direction within the tube and also free torotate therein. The tube is closed at one end by a cap v3 which has anintegral stud 4 rising in a vertical direction therefrom and passingthrough a double frusto-conical passage 5 formed in an attaching plateor bracket 6 which may be screwed or otherwise suitably secured to theframe at the top thereof at a point adjacent to the upper horizontalrail of the easement. The passage 5 has its branches Av and B arrangedso that' the small end of one branch has its walls directly merged intothe small end of the walls of the other branch. ln this manner it isseen that the stud 4 is permitted to rock or turn in the bracket. Atthis point, it is stated that this adjustment is preferred, and in fact,necessary, in order that the device will accommodate itself to a corre.

sponding movement of the easement in a vertical direction. Interposedbetween the cap 3 and the bracket 6 is a spring 7 which serves toprevent undue rattling of the parts.4

At the opposite end of the tube is a cap 8 having a shoulder 9 whichforms a stop against which the coacting shoulder 10 on the rod 2 isdesigned to engage so as to limit the outward swinging movement of therod and, consequently, prevent its entire separation from the tube l.The rod 2 freely slides through the cap 8 and through the tube l and, asshown, it is provided at suitable points in its length with circulargrooves 11.

ment of the rod 2. The outer spring, of course, bears against the plug13 and incident'to the fact that* the latter is sary to a 'equalities inthe movement thereof.

threadedly adjustable within the cylinder, it ofcourse, follows that theIspring' may be p aced under such tension as may be necesroper retentionof therespective parts'1 and 2 of the adjuster. The spherical body orlatch element 14 when extended into anyone of the grooves 11 serves tohold the rod securely inits adjusted position but it does not hindersuch free rotation of the rod as is necessary to'accommodate lateral in-It is desired that the'v friction between at certain times in themovement of the casement so as tolpermit the latter 'to be linitiallymovedV to its open position or to its full closed position, and purpose,the rod is of reduced diameter through a section of its length such asillustrated vat 16. It is seen that when the mentioned reduced portionof the rod is within the tube and disposed at right angles to the axisof the cylinder 12, the ball latch element 14 will'bear` thereagainstand as the i springis not compressed to the extent that it is evidentthat the two parts,

' sage and through it is when engaged in one of the grooves 11, namely,the tube 1 andthe rod 2 may move with more relative freedom and thecasement may then be properly adjusted with relation tothe frame withoutany strenuous or laborious effort of the operator.

The extremity of the reduced end 16 of the rod,2 is provided with apassage 17v which is somewhat similar to the passage formed in thebracket 6. Through this pasthe ears of the bracket 18 is passed a screw19. -The bracket 18 is adapted to be screwed or otherwise suitablysecured tothe easement and as a result of the just-described manner ofconnecting the bracket to the rod, the rod is free to rock slightlyfromfthe bracket. The bracket 18 is, of course, disposed at right anglesto the bracket 6 and by connecting'the tube 1 and the rod 2,respectively, Awith both of the brackets referred to, satisfactorilyaccommodated not only in its described movements but in any otherirregular movements thereof as m'ay result from the)y 'latch memberandthe sliding rod be varied to accomplish this the easement is mostconstantoperation of a structure of this naand horizontal swingingeasements, comprising a bracket adapted to 'be secured to the frame, atube mounted to tilt vertically and swing horizontally from saidbracket,a rod sliding in s aid tube and free to 'oscillate therein andprovided with spaced annular grooves and a yieldingly mounted sphericallockingbody lcarried bysaid tube and adapted to be .successivelyprojected into said grooves as vthe rodis adjusted longitudinallytherein.

A holding device for vertically movable and. horizontally swingingeasements, comprismg, tally and to tilt vertically from the frame, a rodadapted to be mounted to swing horizontally and' to tilt vertically44from the casement and with the tube and mounted to slide in said tube,a member having a stop, said member being secured to the tube, a stopformed on the `rod and adapted Vto coact with the first stop,'and alocking device carried byl said member and adapted to co- 4act with therod to hold the latter adjusted in the tube.

In testimony whereof I aflix my signature in presence of two witnesses.
